Yellow service engine message light along with gas pump icon

Check your owners manual. It should have a page dedicated to telling you what all the warning lights mean. You'll be surprised how much you never knew about your car. Than the next best thing to do is to take it to a quality shop in your area, and have them check it out.

Make sure you tighten your gas cap...emmision issue....have car checked asap. I had this issue it was oil and transmission gasket leakage in my case.
